Problems solved by technology
This mechanism is more expensive, and requires the injection molding machine to output several electronic signals to realize the mold opening sequence, which cannot be used on ordinary injection molding machines
Therefore, mold opening technology has become a bottleneck restricting ordinary injection molding machines from installing T molds for production

Embodiment Construction
[0014] The present invention is a cycle mold opening mechanism used for T-die to make two sets of parting molds not open at the same time. It uses the mold opening and closing action as the power, and is converted into a cycle opening action through mechanical components to realize T-die cycle. Open the mold at the same time.
[0015] see figure 1 , figure 2 , the present invention consists of two tongue seats and an intermediate base, wherein the two tongue seats are arranged symmetrically on both sides of the base, and each tongue seat consists of a tongue seat body 1, a tongue 3, a tongue spring 12 and a tongue spring Bolt 13 forms. Wherein, the lingual plate seat on the left side is fixed on the rear template 15-1 of the A mold, and the tongue plate seat on the right side is fixed on the rear template 17-2 of the B mold. The rear part of the tongue plate 3 is hinged with the tongue plate seat through the pin shaft 2, the tongue spring 12 touches and presses the top of ...

Abstract
The invention provides a cyclic mould opening mechanism of a plastic mould. The mechanism provided by the invention comprises two clapper seats and a middle base, wherein the two clapper seats are arranged at two sides of the base symmetrically; each clapper seat comprises a clapper seat body, a clapper, a clapper spring and a clapper spring bolt; the clapper is hinged with the clapper seat body by a pin shaft; the clapper spring is vertically pressed at the upper part of the clapper; the clapper spring bolt is in threaded connected with the clapper seat, and the bottom of the clapper spring bolt presses the clapper spring; the front part of the clapper is symmetrically provided with lock cylinder buttons; the middle base comprises a base body, lock cylinders, a lock cylinder spring and a lock cylinder spring bolt; the middle part of the base body is provided with a clapper slot and a lock cylinder slot; the clapper slot corresponds to the clapper, and guide slopes are symmetrically arranged at two sides of the bottom of the clapper slot; the lock cylinder slot is located at the middle part of the clapper slot and perpendicular to the clapper slot; the two lock cylinders are respectively located at two sides of the lock cylinder slot; the lock cylinder spring horizontally presses the lock cylinders; the lock cylinder spring bolt is in threaded connection with the base, and the bottom of the lock cylinder spring bolt presses the lock cylinder spring. The mechanism provided by the invention is composed of mechanical members; the condition requirements on injection machines are low; the movement reliability is high; and the manufacture cost is low.
Description
technical field [0001] The invention relates to a mold, in particular to a plastic mold circulation mold opening mechanism, which belongs to the technical field of molding. Background technique [0002] With the improvement of the industrialization efficiency of plastic products, T-die (Tandem Mold) is gradually used. The T-mold is composed of two back-to-back molds with two parting surfaces, and the injection molding process is staggered in the two parting surfaces. Staggered injection molding is the biggest difference between T-mold and stacked molds. In short, T-mold technology adds a staggered injection molding process to use the idle time of the injection molding machine for product cooling. If the T-mold technology is to meet the requirement that the two molds are not opened at the same time, a device is needed to control the mold opening sequence. At present, there is a cycle mold opening mechanism, which controls the movement of the mold opening cylinder by collect...
